Transportation of respiratory gases
Transport of oxygen
98% of the oxygen that is transported from the lungs to the requiring tissues travels within our red blood cells, carried by haemoglobin.
Globular protein,
Quaternary structure
Iron
Each HAEM group can bind 1 oxygen molecule (O2)
Therefore a haemoglobin molecule can exist in a number of forms:
i. Hb4 0% (saturation)
ii. Hb4O2 25%
iv. Hb404 50%
